SMOKE-CONSUMER.

Application filed July 17,

To all whom it may concern:

Be it known that 1, James RYAN, a citizen of the United States, residing at Grand Rapids, in the county of'Kent and State of ichigan, have invented certain new and useful Improvements in Smoke-(misumers for Locomotives, of which the following is a specification.

My invention relates to improvements in forced draft appliances for locomotive boilers, and its objects are: first, to provide a means whereby a large portion of the smoke escaping from the burning coal maybe returned to the fire box to be re-burned; and, second, to provide a means whereby a large amount of oxygen may be forced to the fire box to increase the combustion therein so that a large proportion of the smoke in the fire box will be consumed. l attain these objects by the mechanism illustrated in the accompanying drawing in which Figure l is a longitudinal section of a locomotive boiler showing the draft circulation, and my a )pliance in position on the outside of the boiler. boiler cut away to show my appliance applicdinside of the boiler, and Fig. 3 is a longitudinal section of the appliance showing a valve in the trun'ipet end of the pipe, and the ingress of air back of the conjunction of the pipe that returns the smoke to the main conductor, and, also, showing a means for ma;- nipulating the valve in the trumpet end of the main conductor pipe. p

,7} represents the locomotive boiler. 2 re resen ts the flues and 3 represents the fire ox having any available form of-grates, as 10, for burning the necessary fuel for producing steam. It is a well known and generally accepted fact that from sixty to eighty percent. of the heat. generated in an ordinary the box upon locomotives is carried oll'through the smoke stack 12, and to obviate this great waste 1 have. provided for capturing a portion of the. carbon thrown oil from the fuel in the tire box, in the form of smoke, &c., and returning it to the. lire box thoroughly intermingled with oxygen by reason of a strong parts inflow of air, induced by the rapid move- .anent of the. locomotive.

The arrows 9 reproscnt the passage of heat, smoke &c., from the lire box into and through the tubes 2, and the Specification of Letters Patent.

arrows 9 representthe passage of said heat, smoke &c., into the breeching and through the smoke stack 12. ha ust pipe through which the exhaust steam is forced from the engine cylinders. This pipe exhausts directly under the smoke stack 12 and induces a, so called, forced draft through the flues 2. I

To make my device available I find it very advantageous to divide the opening at the the smoke stack 12 by a partition 11 of any desired form, from a point at the end of th boiler above the fines 2 diagonally down to a ut leaving a space below the lower end as a fine for the passa e of heat, smoke &c., as shown in Fig. l. il-laving arranged this por tion of the appliance I place a pipe 4-. the length of the boiler, thefront end of said pipe being made bell shaped, as at 5, so that it vill collect as much air as possible consistent with the capacity of the me; and'the other end of the pipe is curved and made to ass into the fire box, as shown at 6, so that a air that is collected by the bell 5 will be forced into the iire box, as indicated by the arrows 9. Thus far the only advantage gained is the greater amount of oxygen that is forced into the. tire box to facilitate the combustion of the fuel, but I attain a fu'rtlier advantage by placing a branch pipe, 7, down from the main pi )e 4 and forming a bell thereon just below the partition 11,- near the end of the boiler so that the flow of air through the pipe 4, as hereinbefore described, will si'phon the surplus smoke from the fines 2 into the pipe 4 and thence, with the current of air, through thoroughly mixed with the onrushing air, the surplus of oxygen that is mixed with the smoke renders a heat sulliciently intense to cause nearly all of the carbon contained in the smoke to be consumed, thus not only increasing the combustion of fuel in the tire box, but providing, at small cost, an almost perfect smoke consumer, and with no addi- -'tional effort outside of the natural resistance train.

The pipe 4 may be placed outside of the boiler, as shown in Fig. 1, or it may be passed through the boiler, as shown in Fig. 2, atuFI deem the latter position the best as the inpoint beyond the line of the exhaust pipe 8,,

8 represents the exback of the boiler and immediately under hi5 said pipe and into the lire box 3, where, being of the atmosphere upon a rapidly rl'ioving V -to pass, and with reater force.

from the back in Fig. 3 insures a perfect siphoning forth the appliance in its simple form. Its

efliciency may be greatly increased b the use of proper valves properly manipu ated,

I thus, in Fig. 3 I have shown a very desirable form of valve which consists of a funnel sha ed lining 5 inside of the bell 5 of the .pipe 4, liaving a long rejecting end that is divided, as indicate by the line a, so that if the valve is held in the position indicated by its solid lines the opening at the end of the rojecting pi ewill be small and cutoff the how of an t rough it, while if the valve is rejected out, as indicated by its dotted ines the openin into the pipe 4 will be larger and will al ow a greater volume of air With this valve-I have provi ed for holding it in normal position, indicated by the dotted lines, by means of a spring 0 acting upon a lunger b, which plunger is connected with t e arm 5,-which is into ml with the valve so that an motion oi? t e plunger will move the va ve accordingly, and to actuate the valve against the spring I provide an actuating rod, as d, that is designed to pass back to the cab back of the fire box where it will be easily accessible to the en ineer or fireman who can, thereby, manipu ate the valve as he or'they may desire. It is to be understood that I do not describe this as the only form of valve, available for use upon this de 'vice, but simply as one of the many forms that may be applied for the purpose stated. Another modification shown 1n Fig. 3 is the division of the main pipe into two chan nels, as 4 and 4, the channel 4 entering the pipe 4 some distance back of the entrance of the pipe 7 so that there can be no possible danger of the air that enters the hell '5 being forced back through the pipe 7 and thus prevent the free assage of hot air and smoke end of the fines 2 to and through the pipe 4, as the connections shown of air through the pi e 7 into and through the pipe 4, as' ereinbe'ore stated.

Having thus fully described my invention,

aeaeeo what I claim as new and desire to secure by Letters Patent of the United States, is

1. In combination with a locomotiv'e boiler and its fire box, flues and smoke chamber, a partition extending from the boiler head. above the flues'diagonally out and down into the smoke chamber forming a draft flue in the chamber below the partition, an exhaust pipe opening into the smoke chamber above the partition, a pipe havinga funnel shaped front end and extending back parallel with the boiler and curved to enter the iire box near the top of the boiler, and a curved branch pi e having a funnel shaped open end front of t 1e flues below and parallel with the dia onal partition and leadin into the parails pipe back of the funne shaped front en 2. In combinationwithalocomotiveboiler, a fire box, flues, and smoke chamber, a pipe longitudinal of the boiler and having its back end entering the fire box, a branch pipe leading from the smoke chamber into the main pi e and curved to form a continuous channe with the main pipe and having a funnel shaped end inclining downward and outward from the end ofthe boiler above the fines, an exhaust pipe opening into the smoke chamber above the funnel, an auxiliary pipe having a bell shaped funnel at the front end and opening into the main pi e, and valves in the auxiliary pipe for regu ating the how of air through the pipe.
